SHANGHAI (Reuters) — The Chinese
central bank's decision to relax its grip on the yuan has been
welcomed as a sign of financial liberalization, but it is
aggravating concerns among foreign executives and investors about
their exposure to China in the near term.

The doubling of the trading band from Monday points to much greater
downside risk in a currency that many investors have treated as a
one-way appreciation bet for years, even when the yuan's daily
trading range was expanded in the past.

But it adds to a combination of factors that had already made these
investors cautious. The central bank had engineered a slide in the
yuan's value, adding to jitters in a market already anxious over the
country's first default on a domestic bond, and signs of slowing
economic growth, highlighted by a dramatic 18 percent fall in
exports in February and sluggish manufacturing.

"The foreign investors who we spoke with before this announcement
were already becoming cautious," said Brian Ingram, chief investment
officer at Ping An Russell Investment Management in Shanghai. "I
think this announcement adds to the short-term or near-term bear
case for those investors."

The central bank said that from Monday it would allow the exchange
rate to rise or fall by 2 percent from the official guidance rate on
any given day. Previously the range had been 1 percent.

The move was welcomed by economists as a sign that Beijing is
following through on a promise to allow market forces to play a
greater role in the economy.

In theory it means the central bank will meddle less in the market,
although foreign exchange traders suspect the regulator, through
state-owned banks, deliberately pushed the yuan down this year to
shake out those speculating on one-way appreciation of the currency.

Still, the risk of greater volatility implicit in a wider trading
band will make already nervous investors more cautious.

Companies that sign billions of dollars worth of trade contracts
with Chinese firms, and foreign investors considering whether to
hedge their China bets, may well reduce their level of exposure.

"From some Western investors' perspective, China is just bad, so
anything that looks funny or sounds squirrely means volatility and
less interest," said a senior money manager for an international
investment fund in Shanghai, who spoke on condition of anonymity.

"In general the large institutions, the pension funds, they just see
this as bad news."

The yuan rose 2.9 percent against the dollar in 2013, outperforming
other emerging economy currencies, in a rally that encouraged more
one-way bets and led to a dramatic crack down by the central bank.

UNCERTAIN

These various risk factors have left analysts increasingly divided
over the direction of the yuan this year. In past years, as the
economy boomed and trade surpluses flooded into the country's
coffers, it was a question of choosing how far the currency would
rise.

Now forecasters are less certain and wonder if the government had
other motives behind Saturday's announcement.

"We have all been surprised at the sell-off of the yuan versus the
dollar," said Michael Woolfolk, global markets strategist at BNY
Mellon in New York.

"It was down near 6 and now above 6.10. We are scratching our heads
and wondering if the beginning of a trend reversal is being
orchestrated by the government ... Everyone is afraid of a slowdown
in the Chinese economy."

Lars Christensen, chief emerging market analyst at Danske Bank in
Copenhagen, also questioned the timing of the move and wondered if
the slowdown in economic growth is the real concern for authorities.

"The big question is why they are doing this and to what extent they
are being forced to do it, if outflows have been more than were
thought. So is it a defensive move or a pre-emptive move that opens
the door for monetary easing?"

While the uncertainty lasts, it is a victory for the central bank,
which has struggled for years to get those in the currency market to
shake off the belief that the yuan can only rise.

Reflecting an increasing divergence of views, Li Heng, economist at
Minsheng Securities in Beijing, predicts the yuan will stay flat or
weaken in 2014 to end the year between 6.15 and 6.20 per dollar.

The yuan ended trading on Friday at 6.15 per dollar and is down 1.6
percent so far this year, its sharpest fall since during the Greek
debt crisis in 2012.

One-year non-deliverable forwards contracts, considered the best
available proxy for market expectations of the yuan's future value,
last priced the yuan at 6.2120 per dollar even before the band was
widened.

But HSBC economists believe the recent decline in the yuan, which is
also known as the renminbi (RMB), is not sustainable given China's
durable attraction for investors as the big growth story compared
with other economies, and predicted it will still go on to end the
year at less than 6 per dollar.

"We still expect RMB appreciation to 5.98 versus the USD by the end
of 2014, but the path will be volatile," they wrote in a client
note.

In a sign that the central bank has succeeded in adding uncertainty
to the direction of the yuan, dealers said sentiment has remained
subdued even though intervention by state owned banks has wound down
in the last week or so.

During the Greek crisis, the sliding yuan deterred many corporates
from adopting the currency for use in trade, and the offshore yuan
market saw its expansion stall, implying that much of the corporate
enthusiasm for using the unit was dependent on appreciation
expectations.

Ping An's Ingram said Chinese markets are "going to stay very ugly
for a bit" but that will lead to investment opportunities.

"Once the market can get past all these scares about what is
happening with defaults, all these scares about to what extent
growth is going to slow down, there is actually good investment
opportunity here," he said, citing a cheaper renminbi and attractive
bond yields.

"We are waiting for that opportunity to jump back in."
